CVE-2026-45811

NVD: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in Apache NimBLE. NVD: The HCI socket transport did not check whether a received HCI event would fit the configured event pool before copying it, allowing a buffer overflow. NVD: Severity is low: exploitation requires either a misconfigured pool size or a malicious/compromised controller on the other end of the HCI socket link, not over-the-air Bluetooth access.
